STROPPING DEVICE FOR SAFETY-RAZOR BLADES.

Application filed. December 21, 1927. Serial. No. 241,655.

The present invention relates to devices for holding safety razor bladesduring the process of honing or stropping such blades, the inventionresiding in certain improve ments upon the razor stropping deviceillustrated and described in United States Let-- tors Patent to DuFresne, No. 1.,l89,631, dated April 8, 1924-.

In common with the device of said Du Fresno patent, the device of thepresent invention employs means by which the razor blade may be shifted,in order to expose either edge for stropping or honing, while at thesame time protecting and shielding the opposite edge. According toourinvention, the actuating member of this bladeshitting means is made alsoto serve as a latching device for the hinged cover of the bladeholder,-a construction which greatly simplifies the manufacture of sucha razor stropping device and decreases the cost thereof. Other andfurther objects and advantages oi? the invention are set forthhereinafter, reference being had to the. accompanying drawings, inwhich- Fig. 1 is a side view of the device embodying our invention, withthe hinged cover in open position.

Fig. 2 is a similar View of said device, showing the razor blade in adifferent position.

Fig. 3 is an edgewise View, partly in section, showing the cover inclosed position. v

Fig. 4t is fragmentary detail view, on a larger scale, illustrating thecover-latching function of the blade-shifter;

Fig. is a fragmentary detail view showing the latching devices insection.

Like reference characters refer to like parts in the dilierent figures.

in the coiistructioil. illustrated in the drawings, the device consistsof a handle portion 1 and a blade holding portion 2, and in themanufacture of these parts a single integral strip 3 of metal orothersuitable material is pressed or otherwise appropriately shaped toprovide the rear half of the handle 1 and the back or bottomof the bladeholder 2. The other half of the handle 1 is formed by a piece 4, whichmatches the handle portion of strip 3, the two halves being suitablyjoined together, as by rivets ,5 and 6. A. hinge 7 at the extreme end ofby its medial openings upon a plurality of V studs 9, 9 provided by abar 10, which latter is shirttable within the blade carrying portion 2;of the device between the flanges 1.1, 11 thereof. .To this end,-saidbar is pivotally attached, as shown at 12, to an under lying arm 13,said arm having a slot 14 through which passes a rivet 15, in order topivotally secure the arm 13 to the memher or strip 3. The arm 13 extendsinto the hollow handleportion 1 and i provides two lateral extensions 16and 17, which project through suitable slots 17 formed at the meetingedges of piece tand strip 3, as shown in Fig. 5. A. compression spring18, secured to and hearing at one end against the rivet 5, and at theother end encircling a central projection 19 of the arm 13, is operative normally to thrust said arm 18 outwardly, toward the blade-holdingportion of the device, so that one'end of the elongated slot 14-. bearsagainst the pivotal rivet 15. In this normal position of the arm 13,said arm is operative, by pressure of the finger or thumb against eitherof the projections 16 or 17 to dispose the razor blade 0: into theposition shown in Fig. 1, or into the positionshown in Fig. 2, it beingunderstood that in moving to either of said positions, the edge of theblade is projected through narrow slits left between the meetinglongitudii'cil edges of the bladeholding portion 2, when thecover 8 isin closed position, the same as in the construotion. of the aforesaid DuFresue patent.

As shown in Figs. l and 5', the free end of cover 8 is provided with aprojection 20 and the: material of arm 13 has a struck-up portion 21,whose free end is bent outwardly,as at 22, for cooperation with the tion20 against the bent portion 22, the com tacting faces of these two partsbeing so inclined as to produce a wedging action that thrusts the arm 13inwardly against the force of spring 18. This inward yielding of arm 13allows the projection 20 to snap under the bent portion 22, whereby thehinged cover 8 is latched and held in closed position to confine therazor blade for the stropping operation. As in the aforesaid Du Fresnepatent, first one edge and then the other edge or the blade is stropped;either edge can be projected into stropping position by simply pressingon the projection 16 or the projection 1'7, as desired.

After both edges have been stropped, the blade can be readily removed bydrawing inwardly on the two projec ons 16 and 17 of arm 13; such inwardmovement against the force of spring 18, hich is allowed by theelongated slot let ot the arm, pulls the bent portion away from theprojection 20 of the cover 8, allowing said cover to spring open underthe influence oil a spring, not shown, provided by the hinge 7; thismovement of arm I") to unlatching position is shown by the broken linesin Fig. i.

We claim,

1. In a device of the class, described, a blade holder having aremovable cover, a blade carried within said holder, and means operableto i iit't said blade carrier for the projection at either edge of theblade into stropping position, said last named means being also operableto release said cover for the removal of said blade from said holder.

2. In a device of the class described, a blade holder having a hingedcover, blade carrier within said holder adapted for sliding movement toproject either edge oi? the blade into stropping position, and unitarymeans for actuating said blade carrier and for latching and releasingsaid cover.

3. In a device of the class described, a blade holder providing a coverwhich is movable into and out of covering relation to the blade, a bladecarrier within said holder adapted for sliding movement to projecteither edge of the blade into stronping position, and latching meansholding said cover in closed position and movable to release said cover,said latching means serving also to actuate said blade carrier.

at. in a device of the class described, a blade holder jin'oviding acover which is movable into and out of covering relation to the blade, ablade carrier within said holder adapted for sliding HIOVUIDQBt toproject either edge oi the blade into stropping position, an actuatorfor said blade carrier l avin a projection serving, in the normalposition or"? said actuator, as a. latch to hold said cover closed, anda yielding mounting for said actuator permitting its retraction torender said projection inel'lective to latch said cover.
